FRAME FOR BRICK-'KILNS.

SPECIFICATION forming part of Letters Patent No. $84-$69, dated June 12,1888.

Application filed October 6, 1887. Serial No. 251,620. (No model.)

To aZZ whom it may concern-.-

Be it known that we, EDWARD M. PIKE, JUsTUs CASTLE, and JOSEPH B.SOHOPP, citizens of the United States, residing at Chenoa, in the countyof McLean and State of Illinois, have invented certain new and usefulImprovements in Door-Frames for Tile and Pottery Kilns; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part.

of this specification. I

Our invention relates to door-frames for tile and pottery kilns; and itconsists in the parts which will be hereinafter described, and pointedout in the claims.

In the accompanying drawings, Figure 1 represents a side view of a kilnprovided with our improved door-frame. Fig. 2 is a perspective view ofthe frame detached, showing the top and bottom tie-bolts; and Fig. 3represents a top plan view of one of the arched frame-pieces, and ahorizontal section of the companion frame-piece, and asection of thebrick, showing theposition of the frame therein. In this view the toptie bolt or rod is broken away, so as to disclose the bottom tie rod.

Like letters indicate like parts in the views.

The letter A represents the brick-work of a kiln.

The door-frame is made in two parts. Each part consists of a verticalside piece, B, having a top or arched piece, 0, formed therewith. Theouter end of each arch is provided with a downwardly-inclined verticalprojection, G. The inner or abutting face of each projection is fiat, soas to conform and lie in close contact with the adjoining face or likeprojection on the companion arch. The inner side of each arch isprovided with a series of flat vertical surfaces, D, which are formed bynotching the arch. Each of these surfaces or faces D is provided with atransverse horizontal opening, E, which passes through the arch. Thevertical frame-pieces B are also provided with a series of transverseopenings, E. E are adapted to receive the threaded ends The openings 13of the tie-bolts and the threaded ends of the bolts on the ends of thebands which encircle the kiln.

F represents a tie-bolt for uniting the two abutting arches of theframe, and G indicates the tie-bolt for securing and holding thelowerpart of the framein a firm fixed position. The bolt or rod Gr, when theframe is in position, lies immediately under the threshold,as shown inFig. 1.

The letter H represents a series of bands, which encircle the kiln.These bands lie one above the other. The ends of each band are providedwith screw-threaded bolts h, and said bolts pass through the openings EE in the door-frame, and serve to hold the frame firmly in position. Theframe is so fixed in the brickwork of the kiln that the front edge, inwhich are the openings E E, are outside the kiln and exposed, so as toreceive the tie-rods and threaded bolts on the bands. The rear part ofthe frame B is in the nature of a flange, and it is smaller than thefront part of the frame. The outer top part of the inner flange, B,presents a uniform curved arch. The difference in the sizes of the frameB B forms a rear recess. The brick-work is formed around the outer sideof the inner piece, B, or within the rear recess of the frame, while theouter part, B, is exposed.

The letter I represents alug on the outer side of each arch. The outerface of each lug I is fiat, so as to firmly engage the fiat face of thenot 1 on the outer end of the tie-bolt F. The faces D on the inner sideof the arch are made flat, so as to conform to the flat face of thenuts, which engage the threaded ends of the bolts on the ends of thebands H.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent of the United States 1. A door-frame consistingof two parts, each part consisting of a side piece and aninwardly-turned top piece forming half of an arch, the outer end of eachof said arch-pieces being provided with a fiat face, each face beingprovided with a transverse opening and a tie-bolt in engagement withsaid openings,substantially as described, and for the purposes setforth.

2. A door-frame consisting of two parts,

each part consisting of a side piece and an inwardly-turned top pieceprovided on its outer inner end with a fiat surface adapted to abut thecorresponding surface on the adjoining top, the outer side of each topor arch being provided with a flat-faced lug, I, the abutting ends ofthe two parts of the frame and the lugs aforesaid being provided withopenings in alignment for the reception of a bolt, and a bolt providedwith nuts for engaging said opening, substantially as specified.

3. A twopart door-frame, each part con sisting in a side piece and a toppiece turned inward, said top piece forminghalf of an arch, said sideand arched pieces being provided with transverse openings, the innersides of the arched pieces being provided with flat surfacesD around thebolt-openings, substantially as specified.

4. A twopart door-frame, each part consisting of a side piece and a toppiece turned inward, said top piece forming half of an arch, each of theframepieces being provided with openings, in combination with the bands11, and means for engaging the ends of said bands in the openingsaforesaid, substantially as described.

5. A door-frame consisting of two side pieces, each piece being providedwith an inwardly-turned top piece, forming half an arch, said sides andtop being provided with openingsfor the reception of bolts, each of saidside pieces and its half-arch being provided in the rear with a flange,the outer face of said flange lying within the outer surface of the mainframe-pieces and arch, whereby a recess is formed, substantially asdescribed, and for the purposes set forth.

In testimony whereof we affix oursignaturcs in presence of twowitnesses.
